Here's a tip: If you get tired of clicking endlessly on the "next 90" link, just type really big numbers in the URL after "discuss?start=" until you get to roughly the period you want... The first archived post in the new forum is from 01/12/2000

If you want really old messages, I think I have them saved from 1995 to mid-1999. Those are the ones I analyzed for my thesis back then.
